Neil, that is why your car is so fast, you are a little high, if i were you i would try to lower that to 12.0 to 12.3 ,, add fuel pressure if you can maybe add some race fuel and see what you have .. with my v8 I am running 10.9 to 11.6 sometimes 11.8 I would like to see 11.9 12.1 at 4000 to 6000 RPM in all three gears. ,,talked to Rudy and we are going to remove some fuel in 2 and 3rd, and around 5500 rpm.
